[TYPO3] lost in setfixed links...

[Grégory Duchesnes]

hi all,

I'm trying to use setfixed links in a custom extension. I've read the  
API, searched examples in extensions such as dmailsubscription,  
sr_feuser_register and t3consultancies but i'm still completely lost :(

Anyone could point me to a document explaining how to use this feature?
What i need to do is pretty simple :
on creation of a record in the database, i need the send a mail to a  
user which contains a setfixed link to change a field (this is exactly  
the same behaviour as a newsletter confirmation link but i need extra  
fields in the mail)

i tried this :

Typoscript :


plugin.tx_contest_pi1 = USER_INT

plugin.tx_contest_pi1.fe_adminLib = USER_INT
plugin.tx_contest_pi1.fe_adminLib {
	userFunc = user_feAdmin->init
	includeLibs = media/scripts/fe_adminLib.inc

	table = tx_contest_hit
	defaultCmd=create

	setfixed=1
	setfixed.approve {
		_FIELDLIST = uid
		is_visit = 1
	}
	
	// Creating
	create = 1
	create.fields = is_visit,user
	create.overrideValues {
		is_visit = 0
	}
	create.userFunc_afterSave = tx_contest_pi1->afterSave
	
	authcodeFields = uid
	
	debug = 1
}



and in plugin :


		$this->conf["fe_adminLib."]["templateContent"] = '<!--  
###EMAIL_TEMPLATE_CREATE_SAVED### begin -->
		<!--###SUB_RECORD###-->

		http://www.mydomain.org/mypage/?1=1###SYS_SETFIXED_approve###

		<!--###SUB_RECORD###-->
		<!-- ###EMAIL_TEMPLATE_CREATE_SAVED### end-->';

		$body = $this->cObj->cObjGetSingle($this->conf["fe_adminLib"],$this- 
 >conf["fe_adminLib."]);



but no substitution of ###SYS_SETFIXED_approve### occurs :(



please help,
Duch
